Background:: The relationship between exclusive enteral nutrition (EEN) and bone status is poorly defined in pediatric Crohn disease (CD). Aims:: The aim of this study was to investigate the impact of EEN on body composition, nutritional status, and bone mineral density (BMD) in an incident CD cohort. Methods:: 18 newly diagnosed CD children starting EEN for 8 weeks were prospectively enrolled and evaluated at baseline and after 8 (T8), 26 (T26) and 52 weeks (T52) from diagnosis. The Fat Free Mass (FFM) and the Resting Energy Expenditure (REE) were measured through Bioelectrical Impedance (BIA) and the BMD was assessed by dual-energy X-ray (DXA). We compared DXA data of IBD patients to the data obtained in 15 healthy controls. Results:: CD children had a significant lower BMD compared to healthy control both at baseline (p<0.0001), and after EEN therapy at T52 (p=0.0004); although at this latest time point CD children had a significant increase of BMD compared to baseline (p=0.0015). The BIA analysis showed a significant increase at T26 and T52 of FFM and REE. T52. FFM measured by BIA and BMD measured by DXA were significantly correlated. Conclusion:: EEN improves nutritional status and bone mineral composition.

Abstract
Background:: The relationship between exclusive enteral nutrition (EEN) and bone status is poorly defined in pediatric Crohn disease (CD). Aims:: The aim of this study was to investigate the impact of EEN on body composition, nutritional status, and bone mineral density (BMD) in an incident CD cohort. Methods:: 18 newly diagnosed CD children starting EEN for 8 weeks were prospectively enrolled and evaluated at baseline and after 8 (T8), 26 (T26) and 52 weeks (T52) from diagnosis. The Fat Free Mass (FFM) and the Resting Energy Expenditure (REE) were measured through Bioelectrical Impedance (BIA) and the BMD was assessed by dual-energy X-ray (DXA). We compared DXA data of IBD patients to the data obtained in 15 healthy controls. Results:: CD children had a significant lower BMD compared to healthy control both at baseline (p<0.0001), and after EEN therapy at T52 (p=0.0004); although at this latest time point CD children had a significant increase of BMD compared to baseline (p=0.0015). The BIA analysis showed a significant increase at T26 and T52 of FFM and REE. T52. FFM measured by BIA and BMD measured by DXA were significantly correlated. Conclusion:: EEN improves nutritional status and bone mineral composition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
